BALE -TI E HOOK.

SPECIFICATION forming part of Letters Patent No. 363,116, dated May 17, 188*].

Application filed March 6, 1886. Serial No. 194,217. (No model.)

To all whom it may concern.-

Beit known that I, EDWARD L. CLARK, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Bale Tie Hooks; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to an improvement in cotton-bale-tie buckles of the class to which belongs the buckle shown in the patent to WVilliam Clark, No. 197,602, dated November 27, 1877. Such buckles, whose parts are in the form of hook-shaped pieces of flat metal, have been made by punching from a sheet of iron, and heretofore it has been deemed impracticable to make them in any other way. The objections to bale-tie hooks so made are that a very considerable quantity of metal is wasted by punching them from a sheet, and that in so punching them it is impossible that the fiber or grain of the metal should follow the line of curvature of the hook, so that it is unnecessarily weak and is apt to be broken or distorted when in use. I have discovered that a tie-hook made of a piece of wrought-iron or steel bent into the desired shape, so that its fiber shall follow the line of curvature, is much stronger and better than the punched hook heretofore used, and that its manufacture is cheaper and less wasteful.

In the accompanying drawings, Figure 1 is a plan view of the complete buckle, the parts of which are pivoted together. Fig. 2 is a plan view of one of the hooks of the buckle, and Fig. 3 is an edge View of the part shown in Fig. 2.

Like symbols of reference indicate like parts.

In making my improved baletic hooks I take a thin flat strip of wrought-iron or steel, and by the use of a mandrel and bending devices of suitable construction I bend the strip, or a part of it, edgewise into the hooked shape shown in Fig. 2, the strip being cut into the required lengths either before or after the bending process. The result of the bending is to cause the fiber of the strip to follow the line of curvature, as indicated symbolically by the lines a in Figs. 1 and 2, in which a represents the hook itself. To constitute the buckle two hooks are'punched with eye-holes at their inner ends, and are then pivotally con nected by means of a rivet or pin, I).

These bale-tie hooks are stronger and otherwise better and cheaper in their manufacture than others of the same class which have heretofore been punched out of a sheet of metal.

I claim as my invention-- A curved bale-tie hook of the character specified, made of a flat strip of wrought-iron or steel bent edgewise into the desired shape, whereby the fiber of the metal is caused to follow the line of curvature, substantially as described.

In testimony whereof I have hereunto set 65 my hand this 4th day of March, A. D. 1886.
